backupcopy_list A list of backup copies to delete. Accepts a search query that identifies backup copies. The search query can be a list of
backup copy names or IDs separated by semicolons (;), or a full search. (Required)

cascade Set to 1 to delete the backup copy and any subsequent incremental backup copies on the same machine. The default is 0.

This task deletes the specified backup copies from the host that they are stored on. If the last copy of an incremental backup
is deleted, the corresponding full backup is marked as final, so that no further incremental backups can be created for that database. The next backup run on the database must be a full
backup. When the last copy of a backup is deleted, the backup itself is also deleted.

The host that the backup copy is deleted from must have a cloud server running on it.

If the cascade parameter is set to 1, then the backup copy and its subsequent incremental backup copies (on the same host)
are deleted. If cascade is set to 0, then an error occurs if the specified backup copy is a full backup that has incremental
backups, or an incremental backup that has subsequent incremental backups.
